gem: RFC: add support for private objects

2012-08-17T08:18:46+00:00

These small changes should allow GEM to be used with non shmem objects as
well as shmem objects. In the GMA500 case it allows the base framebuffer to
appear as a GEM object and thus acquire a handle and work with KMS.

For i915 it ought to be trivial to get back the wasted memory but putting the
system fb back into stolen RAM and in general I can imagine it allowing the
use of GEM and thus KMS with all the older cards that have their framebuffer
firmly placed in video RAM.

drm: Fix authentication kernel crash

2012-02-13T20:15:01+00:00

BugLink: http://bugs.launchpad.net/bugs/926309

commit 598781d71119827b454fd75d46f84755bca6f0c6 upstream.

If the master tries to authenticate a client using drm_authmagic and
that client has already closed its drm file descriptor,
either wilfully or because it was terminated, the
call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory
and corrupt it.

Typically this results in a hard system hang.

This patch fixes that problem by removing any authentication tokens
(struct drm_magic_entry) open for a file descriptor when that file
descriptor is closed.

drm: integer overflow in drm_mode_dirtyfb_ioctl()

2011-12-12T13:07:02+00:00

BugLink: http://bugs.launchpad.net/bugs/902312

commit a5cd335165e31db9dbab636fd29895d41da55dd2 upstream.

There is a potential integer overflow in drm_mode_dirtyfb_ioctl()
if userspace passes in a large num_clips.  The call to kmalloc would
allocate a small buffer, and the call to fb->funcs->dirty may result
in a memory corruption.

drm/i915: Fix typo in DRM_I915_OVERLAY_PUT_IMAGE ioctl define

2011-08-16T01:31:35+00:00

commit 842d452985300f4ec14c68cb86046e8a1a3b7251 upstream.

Because of a typo, calling ioctl with DRM_IOCTL_I915_OVERLAY_PUT_IMAGE
is broken if the macro is used directly. When using libdrm the bug is
not hit, since libdrm handles the ioctl encoding internally.

The typo also leads to the .cmd and .cmd_drv fields of the drm_ioctl
structure for DRM_I915_OVERLAY_PUT_IMAGE having inconsistent content.
